OPERATING MECHANISM FOR..;D UMP-DOOR WINDING-SHAE'lJS.

A pneatmnnledsanrn g To 'aZZ whomit may confer-22 Be it known that I. RALPH G. TAYLOR, a

citizen of the United States of America, and

resident of Davenport, Scott county, Iowa,

have invented a certain new and useful Iinprovcmcnt in Operating Mechanism for Dump-Door \iindmg-Shafts, of which the following is a specification.

door operating mechanism for dump cars and particularly tothat-type of mechanism as shown in my copending applications Serial Xo. (55S0O0-filed Xov. 1st. 1911 and Serial No. (38051 creeping ding sh'iift is" employed, having eithen ayvrticiil or lateral movement rela-' tive to the-car-body; and its principal 0b ect. is to maintaln the operating ratchet, the,

ratchet pawl and the pawl locking dog in fixed relation one to the other regardless of the position of the winding shaft in its creeping movement. the mechanism illustrated in the accompanying drawings, in which' i Figure 1 is a side elevation of the end of a body bolster of a dump. car, showing my device in place. F 2 preferred form of ratchet pawl. Fig. 3 is the pawl plate in perspective. F igs l, 5 and 6 are parts of the operating mechanism. Fig. 7 is the body bolster braeket'in perspective. Fi 8 isaplan view of the operating device; Fig. 9 is a side elevation of my device as applied to the underside of a side dump hopper. F igs. l0 and 11 are the preferred form of pawl and locking dog shown infFig. 9. Fig. 12 is a perspective of pawl plate shown in Fig. 9. Fig. 13 is a sectional view taken on line A-B of Fig. l.

Similar numerals refer. to similar parts throughoutthe several views.

To the end of the body bolster'i, which carries the floor sheet 3in the usual manner, is securelv riveted the sh'a ft bracket 5, and the car stake 4 riveted to the outer face thereof in the usual manner.

The square end of the winding shaft 6 extends suflicientlytln'ough slotted opening is provided with a square opening to snugly fit the shaft. Next to theouter race of and loosely sleeved over the extending hub of the ratchetis the operating lever socket being held in place by the washer 15 which 1s vpinned to the end. of the shaft. Next to the Specification ofiL'efitte-rst-Patent.

inner face of the ratchet, between it and the bracket is the pawl plate 9, which slidingly engages pintle 5*, extending from bracket 5 through the slotted opening 12 and also engages the hub portion ll of fatchet 7 through the circular opening 13. It is thus. to be seen, when the ratchet is rotated by lever socket 8 (and pawl not shown) and My invention relates to improvementson;" moves'laterally with the shaft it will'swing the pawl plate about the pintle 5; and'as ratchet pawl 11 is pivotally mounted on pintle 10 which is integral with the pawl plate 9, it also must move with the pawl plate, maintaining its operative position with the ratchet regardless of thelocation of the ratchet in theslotted opening 16 of bracket- 0 during the creeping movement o the shaft.

Fig. 1 shows my improved device as applied to a creeping shaft, having lateral movement relative to the car body, while Fig. 9 shows the device applied to a shaft having vertical novemenh, ,Ilithe latter construction the bracket 17 is secured to the un-dersideof a hopper slope sheet or other convenient place on carloody and provided with a large vertical opening in which shaft 6 is vertically movable. Bracket 17 is also provided with the integral 'pintle 17 about which pawl plate 9. is made to swing through the slotted opening 12. Opening engages the hub ofrat-chet 7. Thus as ratchet and shaft move verticallythe pawl plate must swing also, carrying with it ratchet pawl 18 andv lockingdog 19., which are pivotally mounted'onpintles 10 and 20, thereby keeping pawl and'dog in fixed relation to the' ratchet 7 regardless of its position in its up and down travel.

What I-claim as my invention isg 1. In combination a winding shaft bracketprovided with a pintle extending laterally therefrom.- a winding shaft and ratchet, a pawl plate jonrnaled on said ratchet and slidingly engaging said pi ntle.

2. In combination a winding shaft b 'acket provided with a slotted opening, a windingshaft adapted to travel in said opening, a ratchet adapted to rotate said shaft. a pawl plate swingingly attached to said bracket. and actuated by said shaft substantially as described.

3. A movably supported winding shaft. a ratchet secured to said shaft and provided with extending hub portions, a pawl plate swin'gingly mounted on said ratchet hub exand means to maintain sam'e'infixed relal0 tension, a ratchet pawl and locking dog eartien to said movable shaft.
